None

The file is programmed into flash memory if it is not already present. On subsequent
boots the file in flash is not updated, even if it has changed on the SD card.

Auto

The V2M-Juno motherboard firmware determines if the file on the SD card is
consistent with the file in flash memory. If not, the flash memory is updated.

Force

The V2M-Juno motherboard firmware programs the flash memory with the contents of
the file on the SD card at every boot, regardless of whether it has changed or not.

ADDRESS

The base address within the flash memory that the image is programmed to. The address must
always be prefixed with

0x

.

NAME

The path to, and name of, the file that is programmed. All paths must be specified from the root
of the SD card filesystem.

LOAD

Leave as zero unless required.

ENTRY

Leave as zero unless required.

2 Configuration
